"Living forever and superpowers."

Okay, that doesn't sound very appealing right now but is indeed probably good. Unless immortality sucks, maybe immortality sucks.

"What sort of superpowers?"

“Lots of different kinds. But you’re going to need food.”

"Why am I going to need food?"

“You’re going to make a cocoon.”

Eww

"Why am I going to make a cocoon and what happens if I don't?"

“So it can make your body better and… dunno. Probably nothing good.”

("Okay, is there any way here that Riley can avoid making a coccoon like some kind of bug person!?"

On the one hand, making a cocoon, which is really weird and so probably dangerous. On the other hand

"'Probably nothing good' sounds bad."

"Gah. Look at that guy acting like this is all fine.")

"AM I GOING TO TURN INTO SOME KIND OF BUG PERSON!?"

“Probably not?”

"Probably not?"

The boy shrugs. "You seem really against being a bug person." 

"Of course I'm against being a stinking bug person!"

"Then you probably won't be!"

Since the magic boys apparently aren't going to be helpful, Riley is going to turn around and run back towards home.

---It's like a rent full of fire opening up in her stomach. She's ravenous.

She's going to sit down for a bit. Then she'll go look for a takeaway place, she still has Mom's credit card.

The boys follow.

"How you feeling?"

"Hungry."

"Yeah, you're gonna have to eat. A lot."

"Meh."

Riley continues looking for a fast-food place.

The rainbow boy takes her by the hand and pulls her into a fried chicken joint.

"Our friend needs food!" he declares brightly to the people inside.
